Question about 2001 Ford F150 Styleside SuperCrew
Engine is missing whenever I shift gears and the motor is revving anywhere from 1000-1800 rpm. I guess you could call it a ''sputter'' and it chokes up and then once it gets around 2000 rpm the sputtering/choke subsides and it runs smooth. I have the 6 cylinder 2001 F-150 flareside 4x4 sport.
MAF sensor and IAC valve needs cleaning...use MAF cleaner only....also check for any engine codes...

SOURCE: 99 F250 V10 Sputtering
It takes just one of the coil on Plug units to cause sputtering and severe shaking. Fortunately the prices have dropped slightly for the coil units. The bad news is it is still close to 100 bucks from the Ford dealers. I have had to replace 3 of these on my 1999 F250 superduty V-10 since I bought it new. I believe there may be some compatible aftermarket units out there for high performance V-8 engines, but can not confirm compatibility.

To do this in park or neutral is normal. To do it while driving is not.
There are so many things that could cause this but if you have no check engine light and it runs normally up until then I would suspect you have an exhaust restriction. This can be checked fairly easy on this vehicle, it has a DPFE sensor that mounts near the top back side of the motor.It will either be black or silver,will have a 3 wire connector to it and 2 hoses going down the back of the motor to the exhaust. You can disconnect one of these hoses and install a vacuum/pressure guage and measure exhaust back pressure. It should be 1 psi or less at idle and when you go to wide open throttle should not exceed 3 to 4 psi. If it does something in exhaust,most likely one of the catalytic convertors is stopped up.
